Price is more important than anything of standard items. The needle of a hundred yen shop is weak and the material is weak and it will be bent ... only it will be garbage if you buy it a lot. So it is no good not to buy such things that have a solid quality.

After all, the quality is different. Shin of staple of 100 yen shop is caught in trouble and breaks down. After all, COSPA is bad.
Stable, quality things are smooth, you do not need time to repair the trouble.

Purchased 5000 packs with 5000 bottles. The contents break apart when opened. Most needles are split in two or three. Loading is a hassle. Because it is an inexpensive expendable item, we do not say the exchange, but we would like you to be careful for the future.
